OCT imaging of normal esophagus. (a) Conventional endoscopy of the esophagus showing smooth pale mucosa. (b) Corresponding OCT image showing a well-defined, layered architecture. The epithelium, lamina propria, muscularis mucosa, submucosa, and muscularis propria are seen as distinct layers with alternating hypo- and hyperintensity.
